PERM UTATlON-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 611,982, dated October4, 1898.

Application filed July 7,1897. Serial No. 643,748. (No model.)

To aZZ whom it may concern.-

Be it known that LGEORGE W. STANLnY,residing at Elkhart, in the countyof Elkhart and State of Indiana, have invented a new and useful Padlock,of which the following is a specification.

My invention relates to improvements in that class of padlocks known aspermutation-padlocks.

The object of the invention is to provide a simple and improved lock inwhich the combination may be quickly and readily changed when desired,the construction being simple, cheap, and effective.

The invention consists in the details of construction hereinafter fullydescribed in the specification and specifically pointed out in theclaim.

In order that my invention may be fully understood, I will proceed todescribe the same with reference to the accompanying drawings, in which-Figure 1 is a perspective view showing the padlock in locked position.Fig. 2 is a sectional view thereof. Fig. 3 is also a sectional Viewtaken on the line 3 3, Fig. 2. Fig. 4. is a detailed section taken onthe line 4 4. Fig. 5 is a detailed section taken on the line 5 5, Fig.2. Fig. 6 is a detail View of one of the permutation-disks.

In the said drawings, A represents the loop or stationary part of thepadlock, having the screw-threaded ends, to which are fixedlysecured thesleeves B and C by brazing or welding. The sleeve B is adapted toreceive one end of the shackle D, and it is provided with any suitablemeans to prevent that end of the shackle from being withdrawn, butpermitting the shackle being turned,while the sleeve 0 is formed withthe enlarged portion 0, which serves as a base for the permutationdisksE, and the slot 0 to accommodate the feather on the shackle end. Thesleeve 0 is further provided with the screw-threaded end E, on which thelocking-disk F. fits. The said locking-disk is held thereon by means ofthe screw F, embedded in the manner shown in Figs. 2 and 5, so that thedisk cannot be taken off to change the combination until the screw F isremoved. When the shackle is in a locked position, the disk G, which isformed integral with the shackle, rests over the screw F to prevent itsbeing taken out.

The permutation-disks E are formed with the central opening and the gateT, and they are recessed on their faces to allow of washers II beingplaced between them, so that one disk can be turned without interferingwith the adjacent disk. They are also provided with projections I ontheir periphery,on which are placed letters or numbers, as preferred,which go to make up the combination-lock,

and one of these projections is placed in line a with the gate T. Asshown in Fig. 3, the feather M on the shackle end is formed with thecut-out portions, in which the flange M of the disks fits when the disksare in disassembled position.

The on anner of assembling the various parts in my device is clearlyshown in the several views of the drawings, and the operation thereof isas follows: The disks are arranged on the sleeves G in any desiredarrangement to form a combination, and the combination is formed byturning the several disks until the letters or numbers indicating thegates of t the disk are in line with the indicator N, carried by thelocking-disk. When the disks are in this position, it will be seen thatthe shackle can be withdrawn to unlock the padlock. WVhen the shackle isreturned, the disks are turned to destroy the combination, thus bringingthe flanges M of the disks in the cut-out portions of the feather, sothat the shackle cannot be withdrawn.

Having thus fully described my invention, what I claim as new, anddesire .to secure by Letters Patent, is-

The combination of the loop A, having the sleeves B, C secured to itsends, the sleeve 0, being longitudinally slotted and provided with theenlarged end 0, the shackle D fit-.

ting into the sleeves with notched feather to enter the slot, the diskson sleeve (J, having inward-projecting flanges to move in the notches ofthe feather, the rings or washers I-I, seated between the disks, anduponthe feather between its notches, the locking-disk F, threaded onsleeve 0, the screw F, locking the disk F, and the flange G, on theshackle covering the head of screw F, -substantially as described.
